The chestnut-fronted macaw was
formally described in 1758 by the Swedish naturalist
Carl Linnaeus in the
tenth edition of his
Systema Naturae. He placed it with all the other parrots in the
genus Psittacus and coined the
binomial name Psittacus severus. This macaw is now one of the eight extant species placed the genus
Ara that was erected in 1799 by the French naturalist
Bernard Germain de Lacépède. The genus name is from
ará meaning "macaw" in the
Tupi language of Brazil. The word is an
onomatopoeia based on the sound of their call. The specific epithet
severus is
Latin meaning "grim", "cruel" or "stern". The species is considered to be
monotypic: no
subspecies are recognised. ==Description==
